Repro steps
- Visit an article which is not in main space - e.g. starts with Wikipedia: or User: e.g. User:Etonkovidova/sandbox
- When such articles made their way to Home page to 'Because you read ...' section - they are displayed as a placeholder without content
- Clicking on 'More like User:Etonkovidova/sandbox' bring an empty page
Expected results
- no-main space articles should be treated as other articles
- if there is nothing to direct to (aka 'More like ...') the link should not be displayed.
API Note
MobileView now returns the "ns" field. Only articles in the article space (ns=0) should be used for recommendations.
